I see there are PSI0_VID, PSI0_EN and PSI1 bits defined for use, according to VRM specs they are active low and the VBIOS voltageobject table is not setting any of these bits. Does that mean my system is running 1-phase DE mode? Or there is some logic in driver that switches to 2-phase CCM? Regards, Tom
